Abstract

habitat is fragmented into several regions led to the survival of a population of a species depends on habitat conditions. The purpose of this study was to determine the population density of orangutans based on the number of nests in the Bulumario Village, Nature Reserve area Dolok Sibual Buali, District Sipirok, South Tapanuli, North Sumatra Province also determine the types of dominant vegetation is used as a nesting tree of the Sumatran orangutan in the village Bulumario, Knowing the value and Importance Value Index (IVI) of trees located in the village of Bulumario. This study was conducted in May 2014 until June 2014 in Nature Reserve Dolok Sibual Buali, Bulumario Village, District Sipirok, South Tapanuli, North Sumatra Province  The results of this study indicate orangutan population density based on the number of nests in the Bulumario village and district CADS is 0,023 individuals/km2 or 2,332 individuals/ha of the total number of nests found 49 nests. Most nests were found at a distance of 0-100 meters of the entire track the number of 14 nests (28,57%) and the class that dominates nest class D is the number of 23 nests (46,94%). Dominant position of the nest is in a position which is a position I nest close to the main stem of the tree with the nest number 24 (48,98%). Generally the nest is found at an altitude of 6-10 meters with a sum of 15 nests (30,61%). Important Value Index (IVI) is highest on the type Hoteng (Quercus gamelliflora Blume.) Of the family Fagaceae with IVI 33,83%, and the Moraceae family that is dominated by the number seven species.Keywords: Sumatran Orangutan, Orangutan Density, nest, Important Value Index

Abstract

Changes in landuse and land cover change through forest conversion is the caused of global warming. Due to the climate change, agroforestry systems is estimated to have a high potential for carbon sequestration in the atmosphere. Agroforestry systems contribute to reducing the increase in atmospheric CO2 and other greenhouse gases by increasing carbon in the soil and reduce the pressure for forest clearing, where the carbon comes from CO2 is taken up by plants and stored in the form of biomass. This study aimed to quantified the carbon content and to maped the distribution of carbon in agroforestry stands in Parbaba Dolok Village using data of remote sensing. Calculation of carbon stocks used non-destructive (allometric method).  Vegetation types that exist in distribution of land agroforestry in Parbaba Dolok Village are kopi, coklat, pinus, nangka dan durian. The amount of carbon stocks in agroforestry stands in Parbaba Dolok Village was 337,461 ton/ha. Differences in carbon content acquistion in this area was influenced by vegetation density, diversity of size, and distribution of vegetation density.Keywords: Agroforestry, Carbon Stock, Biomass

Abstract

Deer are wild animals which have been developed in breeding place because their habitat is corrupted. One of the breeding places in developed is CPL (Cinta Pesona Ladangku) breeding place at Kuala Bekala, North Sumatera. The observed parameter was the correlation between bio-ecological aspect and and the population development of deer. The research used descriptive method. The result of the research showed that the minimum of air temperature in CPL breeding place was 220 C and the maximum of air temperature was 340 C. The population of deer in CPL breeding place has surpassed the capacity of the animal pen. Viewed from some bio-ecological aspects, Bawean deer could not multiply in number in CPL breeding place. The age-structure was an upside down pyramid where the number of fawns was fewer than that of deer. The deer breeding technique needs special attention in order to increase the number of deer population.Keywords : Deer, Breeding place, Bio-ecology, Population.

Abstract

is Sumatran Orangutan (Pongo abelii). as a result of orangutan habitat fragmentation, there are problems arised such as conflicts between human and orangutan. This study aims to do mapping conflict area and analyze the biophysical factors that support the conflict between orangutan and the villagers around Dolok Sibual-buali Natural Reserve. By using the coordinates of human-orangutan conflict location, and then processed using Geographic Information System application to identify several factors such as altitude, slope, distance from the river, distance from the road, distance from the forest area, and the land use.  This research showed that the human orangutan conflict-prone area is in the location with secondary tropical dry land forest cover type in the altitude between 742-1051 m asl, at 0-8%, 8-15%, 15-25% range of slope and the distance around 0-4250 meters from Dolok Sibual-buali Natural Reserve area. The result of Rank Spearman correlation test showed that the strongest physical factor effect of this case is the field’s distance from forest area and the weakest effect is the field’s distance from the river.Keywords: Orangutan Sumatra, Human-orangutan conflict,Conflict Area Mapping, Dolok Sibual-buali Natural Reserve

Abstract

Sumatran Orangutan (Pongo abelii) is protected mammal species which existence is now in critically endangered species category of the International Union for Conservation of Nature (IUCN). It’s facing a very high risk of extinction in the wild. This research aimed to estimate Sumatran orangutan density, determined the types of dominant vegetation used as nesting tree, assest the value and Importance Value Index (IVI) of trees located in the village of Aek Nabara. This indirect method was used by counting the number of nests due to the difficulties in finding Sumatran Orangutans in wild habitat. The area of village is  in the border of Dolok Sibual-buali Natural Reserve, South Tapanuli.   The results of this study indicated orangutan population density was 0,006 individuals/km2 or 5,994 individuals/10 ha with the total number of 18 nests. Generally the nest was found at 6-10 meters of tree hight with a sum of 8 nests (44,44%). The highest of Important Value Index (IVI) was Hoteng species (Quercus gamelliflora Blume.). The trees which mostly used by orangutans as a nest was Hau Dolok tree (35,29%).Keywords: Sumatran Orangutan, Orangutan Density, orang utan nest, Important Value Index, Dolok Sibualbuali Natural Reserve

Abstract

Ficus spp. a feed source tree that is a keystone species for primates and birds. Availability Ficus spp feed. This needs to be evaluated. Therefore, the availability of this feed is quantified through Ficus spp abundance. and estimates of productivity growth in young leaves, fruits, and flowers Ficus spp. The methodology used in this research is the analysis of vegetation and Zweifel method. The results were obtained Ficus spp abundance. highest in saplings found in trail 1 (4.325). Ficus spp abundance. relatively rare. Estimated productivity of young leaves in the January to April period of observation ranges from 30% -40%. Estimated productivity of flowers in the period January to April tends to moderate. Estimated productivity of fruit in the January to April period of observation ranged from 1-100 pieces per month. Period fertilization occurs after the flowering period, so the number of pieces that appear influenced by the growing amount of interest. If the amount of interest a little, then the amount of fruit too little. Observation period of January to April, including not tend to dry the fruit season. Other species in ecological niches are black squirrels and hornbills. Keywords: Ficus spp., Zweifel, estimated productivity, species abundance, ecological niches.Keyword: species abundance, productivity estimation, Ficus spp, Sumatran Orangutan, Natural Feed, Gunung Leuser National Park

Abstract

Styrax sumatrana is one of the flagship plant in North Sumatra which has enough potential to be developed. The research was to know frankincense sap productivity Toba (S. sumatrana) with the modification of the physical treatment by being hit and treated with aluminum foil and closed with a combination of both. Making scractch is done by maked cuts in the skin in a vertical line with a length of 2-3 cm with a depth (depending on the thickness of the skin) to the wood. The results showed that treatment with a physical beating and beating and closure combination significantly different physical treatment, closure, while the physical treatment with a combination of beating and beating and closing were not significantly different. The best in productivity of Styrax sumatrana  is beating and combination, the value is 437,82 g/tree/year.Keywords: Styrax sumatrana, sap, modified harvesting techniques, physical treatment
